SHUTTLE-FEELER THREAD-PARTER-OPERATING MECHANISM.

Application filed December 5, 1927, -Seria1 No. 237,640.

This invention relates to filling replenishing looms and is more particularly directed to the shuttle feeler threadparter which is usually employed in such looms to part the outgoing filling between the'shuttle andcloth selvage.

v It is now the usual practice to provide replenishing looms with a shuttle feeler thread parter, or parter and clamp, which acts upon the outgoing filling end on replenishment of filling to'part the filling between the cloth selvage and shuttle. In some cases the parter, or pa-rter and clamp, carried bythe shuttle feeler, has been actuated to perform its partingfunction only upon replenishment of filling, in order that upon failure of replenishment the fillingwill not be parted, which might result in imperfect cloth.

Where the parting, or parting and clamping, mechanism has been actuated only on replenishmentof filling,it has been common to provide a train of mechanism actuated through the replenishing operation to operate the parter or parter and clamp and, in case of failure of replenishment, to fail to part the filling. These mechanisms as heretofore devised have usually introduced complicated parts at a portion of the loom where the parts are alreadymuch crowded, andmanyattempts have been made to simplify the train ofmechanism for causing actuation of the parter or parter. and clamp only on replenishment of filling.

One of the important features of the present invention consists in a simplified means for actuating the parter or parter and clamp only when replenishment is effected. More specifically stated. the parter or parter and clamp in accordance with the present invention is mounted on the shuttle feeler and the transferrer has secured thereto a parter clos ing member preferablyconstituted as an arm secured to the transferrer or a part thereof and having a rearwardly extending end portion normally positioned above the parter or parter and clamp when the latter is in its operating position the effect-being that when the transferrer effects replenishmentof filling the parter or parter and clamp will .be actuated to part the thread between the cloth selvage and shuttle, but should thetransferrer fail to effect replenishment the pa-rter or parter and clamp will not be actuated, so

that perfect cloth will continue to be woven.

The invention and new 'features thereof means.

will best be made clear fromthe following description and the accompanying drawings showing a good practical form thereof.

In the drawings: v

I Looms of the replenishing type are now usually provided with a hopper for containin the filling carriers to be transferred from time to time to the. shuttle when replenishment of filling is indicated by the indicating The indicating ,means for calling into. operation the replenishing mechanism is not shown herein throughout its details becauseit is now Well understood in the art and 'may comprise any usual form of detecting mechlaterally from the shuttle feeler is a stud 6 which is engaged by the bifurcatedend of the arms 7 and S which are themselves associated with the usual transverse or change shaft.

be omitted, but it is preferable to provide It has; not been deemed necessary herein to showthe transverse or change shaft the thread clamp for the purposes above indicated, and the present invention will be described in connection with a thread parter and clamp.

The thread parter and clamp, comprising the parting member 9 and the cooperating clamping member 10, is pivotally mounted upon the stud 11 projecting from the shuttle feeler 4 and, as shown, in Fig. 2, the parter and clamp are indicated in their open position with the shuttle feeler moved rearwardly to its operating position, and the parts so far described may be of usual construction.

Extending from the parter 9 is a pin 12 which is adapted to be engaged by a trip de vice 13 mounted upon an upstanding arm 14- secured to a part of the bracket 2. The trip device may be of usual construction as now common in looms of this type and may act as heretofore to open the thread parter and clamp as the shuttle feeler moves rearwardly to feeling position and to trip by the pin 12 when the shuttle feeler is moved frontwardly, so that the parter and clamp remain closed in front position to hold the end leading to the cloth selvagc for the action of the temple thread cutter. All these parts as thus far described may be of usual or any preferred construction. V

Mounted on the loom frame is the hopper stand 15 which may be of any usual type, but as herein shown is adapted to support a ro- 'tary hopper, as usual, containing the filling carriers 16. These parts may be of ordinary construction.

Mounted in a bearing 17 on the hopper stand is the stud shaft 18 on which is preferably mounted the tra-nsferrer 19, from the hub portion 20 of which is the downwardly extending arm'21 having pivotally connected thereto at 22 the usual. dog 23 adapted to be engaged by a hunter on the lay, as usual, when filling replenishment is indicated. In the present instance, the dog 23 has the lateral ly extending pin 24: which is connected by the arm 25 to the shuttle feeler 4%, the construction being such that on call for replenishment of filling the dog 23 will be moved into the position indicated by Fig. 3 for engagement by the bunter 26 mounted upon the lay, as usual.

All of the parts as hereinbefore described may be of usual construction as may also be the lay 27, which is provided with the usual shuttle box 28 at the replenishing side of the loom.

As hereinbefore stated, the thread parter and clamp is opened by the trip 13 as the shuttle feeler moves backwardly to its shuttle feeling position, and the parting member 9 is provided with a hump or rising portion 29 which extends above the top of the shuttle feeler 4: when the parter and clamp is opened ready for its parting and clamping action.

In accordance with the present invention,

means are provided of simple and effective construction for actuation by the transferrer 1 when it performs its transferring function, so that on call for replenishment of filling the parter and clamp may be actuated to part and clamp the thread, provided only that filling replenishment is actually accomplished.

The parter closing member is constituted as an arm which issecured to a part of the transferrcr and has the laterally and rearwardly extending portion, the terminal end of the latter being normally positioned above the parter and clamp when the latter is in its parting and clamping position.

As shown in the present instance of the invention, the parter closing member comprises an arm 30 having a rearwardly extending securing portion 31 which projects through an opening formed in the downwardly extending member 21 of the transferrer, and such portion 31 of the closing member is adj ustably secured in place by a set screw or bolt 32 whereby the bodily position of the parter closmg member may be adjusted' towards and.

from the front of the loom to properly position the parter closing member for the performance of its function. The portion 2310f the parter closing member extends frontwardly, as indicated in Figs. 1 and 2, and its front portion is turned laterally, as at 33. Extending backward from the portion 33 of the closing member is the arm 3st, the rear terminal end por ion of which at 35 may be projected laterally, indicated in Fig; v1,'in order to present a sufficient engaging portion to act upon the parter. Since theparter closing member is fixed or secured-to the trans ferrer or the rigid downwardly extending arm 21 thereof, it follows thatduring normal weaving operations the parter closing mem her will be maintained in its raised position,

as indicated in Fig. 1, with the terminal'end portion 35 thereof in position to act upon the parter when the transferrer effects replenishment of filling, as indicated 1n Flg. 3. Since the parter closin member is secured to the transferrer or a part thereof and the transferrer itself is pivotally supported on the stud 18, it follows that when the transferrer moves downwardly and effects replenishment of filling, the terminal end portion 85 of the parter closing member will descend upon the projection 29 of the parter and cause the parter to be closed to part andv clamp the thread. i

Preferably the parter closing member is formed of resilient material, as, for instance, elastic wire, which may yield appropriately under continued movementof the transferrer after the parter closing member has closed the parter and clamp, and while'the present invention is'not necessarily limited to the parter closing member as formed of a single piece, as indicated in the present illustration of the invention, yet the simplicity of the .upon the desired portion of the parter single piece parter closing member lends it-v self favorably to the accomplishment'by a simple means of the results sought by a more complicated mechanism.

The adjustability of the parter closing member in its connection with the transferrer or the downwardly extending arm 21 thereof affords a simple and convenient means for positioning theterminal end portion 35 of the parter closing member to act effectively during replenishment.

It will be noted from the disclosures of the present invention that the means for actuating the part-er and clamp to part and clamp the thread is not only directly ass'ociated'with the transferrer, but presents a simple and effective means for operating the parter and clamp only when filling replenishment is effected. Should filling replenishment not beefiected, thetransferrer of course will not descend to its full transferring position,with the result-that the parter closing member will itself not descend.

Since theparter closing member is secured directly to the transferrer or its downwardly extending arm 21, the lateral extension 33 serves to position the backwardly extending portion 34 at the side of the hopper with the end 35 of the parter closing member properly positioned above the parter for action thereupon when and only when filling replenishment is effected.

What is claimed is:

1. In a filling replenishing loom, the combination of a hopper, a pivotally mounted transferrer having a downwardlyprojecting arm provided with an opening from front to rear thereof, a dog pivotally connected to said arm for operating the transferrer, a shuttle feeler having a thread parter, a parter closing member constituted asan arm having a backwardly extending securing end engaged in said opening of the downwardly projecting arm and provided with a lateral bend terminating in a backward extension with its terminal end portion above the parter when in parting position to close the parter when filling replenishment is effected.
